The principal amount of the Note shall be reduced upon any exercise of the Option to Elect Early Termination, all as provided below. Interests in this Note (which are sometimes referred to herein where the context so requires as the "Notes"), and any certificated Notes which may be issued in exchange herefor pursuant to the terms hereof, are issuable in denominations of $100,000 and integral multiples of $1,000 in excess thereof. The Notes are not subject to redemption at the option of the Company prior to maturity. Interest on this Note will be payable on the second Wednesday of each month (each an "Interest Payment Date"), commencing in November 1993, and at maturity. The per annum rate of interest with respect to this Note will be reset monthly on each Interest Payment Date and will be equal to LIBOR (as defined herein), plus 0.05% (five one-hundredths of one percent). Notwithstanding the first paragraph hereof, this Note will mature on the Interest Payment Date occurring in October 1994 unless the maturity thereof is automatically extended with respect to all or a part of the principal amount hereof. During the period beginning on the sixtieth (60th) calendar day immediately preceding, and ending on the thirty-second (32nd) calendar day immediately preceding, each Interest Payment Date (each such period being referred to herein as an "Election Period", and each such Interest Payment Date being referred to herein as the "Interest Payment Date applicable to such Election Period"), commencing with the Interest Payment Date occurring in January 1994, the Holder of this Note will have the option to elect a final Maturity Date (as defined herein) for this Note (or for any interest herein of an authorized denomination) which is the Interest Payment Date occurring on the second Wednesday of the ninth month after the Interest Payment Date applicable to such Election Period. Any or all of the interest herein as to which such election has been exercised is referred to herein as an "Exercised Note". If the Holder of this Note does not so elect, the maturity of this Note shall be automatically extended to the Interest Payment Date occurring on the second Wednesday of the tenth month after the Interest Payment Date applicable to such Election Period. The "Maturity Date" of any Note shall mean the Interest Payment Date occurring in October 1994 or any later date to which the maturity of such Note is automatically extended as described in the previous sentence. The maturity of the Notes will not be so automatically extended to any date after October 9, 1996. The Holder of this Note may elect to terminate the automatic extension of the maturity of this Note or of any interest herein (of an authorized denomination) by surrendering this Note during any Election Period, commencing with the Election Period related to the Interest Payment Date occurring in January 1994, to the Corporate Trust Office of the Trustee in The City of New York (or at such other place as the Company shall notify the Holders of the Notes, provided that the Company shall at all times maintain an office for the exchange contemplated below in the Borough of Manhattan, The City of New York), with notice to Merrill Lynch, Pierce, Fenner & Smith Incorporated, World Financial Center, North Tower, 10th Floor, New York, New York 10281-1307, Attention: Medium-Term Notes Desk (telephone (212) 449-4545), and with the form entitled "Option to Elect Termination" which is appended hereto duly completed. Such notice must be received by the Trustee by 5:00 p.m., New York City time, on the last day for giving such notice. The date on which such surrender occurs shall be the "Election Date" with respect to portion of this Note as to which the automatic extension shall have been terminated. Upon the exercise of an Option to Elect Termination, the principal amount of this Note subject to such election shall be endorsed by the Trustee on the Schedule hereto, whereupon the principal amount hereof shall be reduced for all purposes by the amount so endorsed. The Trustee shall deliver to the Holder in exchange therefor a new Note (substantially in the form of Annex 1 hereto) imprinted with a legend indicating (i) that an election to terminate the automatic extension of the maturity of such Note has been made, (ii) the Election Date and (iii) the Maturity Date with respect to such new Note. Any Note or Notes issued in exchange for or upon registration of transfer of any Notes so legended shall also be legended to the same effect. An election to terminate the automatic extension of the maturity of this Note (or of any portion thereof, as the case may be) shall be irrevocable and binding on the Holder and any subsequent Holder of this Note unless waived by the Company prior to the close of business on the third Business Day following the Election Period during which the Election Date occurs. (In the event 2 that the Holder of a Note issued in certificated form, if any, wishes to terminate the automatic extension of the maturity of a portion of such Note that is an amount equal to $100,000 or an integral multiple of $1,000 in excess thereof, the Holder shall surrender such Note as described above, with the "Option to Elect Termination" form duly completed, in exchange for (i) a Note in the principal amount as to which the automatic extension of maturity has been terminated, legended as described above, and (ii) a Note for the remaining principal amount as to which the automatic extension of maturity has not been terminated and which has not been so legended.) All questions as to whether and when an election to terminate the automatic extension of the maturity of any Note has been made shall be determined by the Company, whose determination shall be final and binding. With respect to any Exercised Note, interest will be payable at such times, and will be calculated by such method, as is provided in the form of Note included as Annex 1 hereto. Interest payable on each interest Payment Date will include interest accrued from and including the first day of the Interest Period relating to such Interest Payment Date to and including the last day of such Interest Period. "Interest Period" shall mean the period beginning on and including October 12, 1993 to but excluding November 10, 1993 and, thereafter, each successive period beginning on and including the day after the last day of the preceding Interest Period and ending on but excluding the next succeeding Interest Payment Date. This Note will bear interest at a per annum rate equal to LIBOR plus 0.05% (five one-hundredths of one percent), and such rate shall be reset each Interest Payment Date other than at maturity (each such date, together with the original issue date of the Notes, October 12, 1993, being referred to in connection with Notes other than Exercised Notes as an "Interest Reset Date"). "LIBOR" with respect to any Interest Determination Date (as defined below) shall equal the rate which appears on Telerate Page 3750, "British Bankers Association Interest Settlement Rates", under the column entitled "U.S.D.", which appears as of 11:00 A.M., London time, on the applicable Interest Determination Date, for deposits (in United States dollars for a period of one month) commencing on the second day on which dealings in deposits in United States dollars are transacted in the London interbank market (a "London Banking Day") immediately following such Interest Determination Date; provided, however, that if no such rate appears, the Calculation Agent shall request the principal London office of four major banks in the London interbank market selected by the Calculation Agent to provide the Calculation Agent with a quotation of their offered rates at approximately 11:00 A.M., London time, on such Interest Determination Date for deposits (in United States dollars for a period of one month and in a principal amount equal to an amount that is representative for a single transaction in such market at such time) commencing on the second London Banking Day immediately following such Interest Determination Date. If at least two such quotations are provided, LIBOR for such Interest Determination Date shall equal the arithmetic mean of such quotations. If fewer than two such quotations are provided, LIBOR for such Interest Determination Date shall equal the arithmetic mean of the rates quoted by three major banks in The City of New York, as selected by the Calculation Agent, at approximately 11:00 A.M., New York City time, on such Interest Determination Date for loans to leading European Banks (in United States dollars for a period of one month and in a principal amount equal to an amount that is representative for a single 3 transaction in such market at such time) commencing on the second London Banking Day following such Interest Determination Date; provided, however, that if the banks selected as aforesaid by the Calculation Agent are not quoting as described in this sentence, LIBOR will be LIBOR in effect on such Interest Determination Date. "Telerate Page 3750" means the display designated as page "3750" on the Dow Jones Telerate Service (or such page as may replace the 3750 page on that service or such other service or services as may be nominated by the British Bankers' Association for the purpose of displaying London interbank offered rates for U.S. dollar deposits). "Interest Determination Date" with respect to LIBOR shall be the second London Business Day (as defined below) preceding each Interest Reset Date. A "London Business Day" is a day on which dealings in deposits in United States dollars are transacted in the London interbank market. Interest on the Notes will be computed and paid on the basis of the actual number of days for which interest accrues in each Interest Period divided by 360. The Calculation Agent will, upon the request of the Holder of any Note, provide the interest rate then in effect. The Calculation Agent is Merrill Lynch, Pierce, Fenner & Smith Incorporated. All calculations made by the Calculation Agent in the absence of a determination of manifest error shall be conclusive for all purposes and binding on the holders of the Notes. Interest shall be paid on each Interest Payment Date to the Holder of this Note on the Regular Record Date. The "Regular Record Date" shall be the date 15 calendar days (whether or not a Business Day) prior to the applicable Interest Payment Date. If the Maturity falls on a day which is not a Business Day as defined below, the payment due on such Maturity will be paid on the next succeeding Business Day with the same force and effect as if made on such Maturity and no interest shall accrue with respect to such payment for the period from and after such Maturity. The interest so payable and punctually paid or duly provided for on any Interest Payment Date will as provided in the Indenture be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such Interest Payment Date. Any such interest which is payable, but not punctually paid or duly provided for on any Interest Payment Date (herein called "Defaulted Interest"), shall forthwith cease to be payable to the registered Holder on such Regular Record Date, and may be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to the Holder of this Note not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner, all as more fully provided in the Indenture. Payment of the principal of and interest on this Note will be made at the Office or Agency of the Company maintained by the Company for such purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto at such address as shall appear in the Security Register. Notwithstanding the preceding sentence, payment of principal of and interest payable at maturity 4 on this Note shall be made by wire transfer of immediately available funds to a designated account maintained in the United States upon (i) receipt of written notice by the Trustee from the Holder hereof not less than one Business Day prior to the due date of such principal payment and (ii) presentation of this Note to the Trustee. The Holder of not less than $1,000,000 Notes may by written notice to the Trustee (or at such other address as the Company shall give notice in writing) not less than 15 days prior to an Interest Payment Date, arrange to have the interest payable an all Notes held by such Holder on such Interest Payment Date, and all subsequent Interest Payment Dates until written notice to the contrary is given to the Trustee, made by wire transfer of immediately available funds to a designated account maintained in the United States.

MERRILL LYNCH & CO., INC. MEDIUM-TERM NOTE, SERIES B (Nine Month Renewable Floating Rate) MERRILL LYNCH & CO., INC., a Delaware corporation (the "Issuer" or the "Company," which terms include any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to , or registered assigns, the Principal Amount of this Note (as indicated above) on the Maturity Date (as indicated above, which shall not be later than October 9, 1996), and to pay interest thereon, as described below, until the principal hereof is paid or duly made available for payment. This Note is a part of a series of Notes originally issued by the Company on October 12, 1993. Pursuant to the terms of such Notes, the Option to Elect Termination has been exercised with respect to this Note, and this Note shall mature on the Maturity Date specified and have the terms and conditions specified herein. The form of this Note as originally issued by the Company, which governed the terms and conditions hereof prior to the exercise of the Option to Elect Termination (the "Initial Note Form") is attached as Annex I hereto. Terms used but not defined herein but which are defined in the Initial Note Form shall have the meanings provided therein. Interests in this Note (which are sometimes referred to herein where the context so requires as the "Notes"), and any certificated Notes which may be issued in exchange herefor pursuant to the terms hereof, are issuable in denominations of $100,000 and integral multiples of $1,000 in excess thereof. The Notes are not subject to redemption at the option of the Company prior to maturity. Interest on this Note will be payable on each monthly Interest Payment Date to and including the Interest Payment Date (as provided in the Initial Note Form) applicable to the Election Period relevant to this Note (the "Last Monthly Interest Payment Date"), and thereafter on the second Wednesday of the third month and sixth month following the Last Monthly Interest Payment Date, and at maturity, "Interest Payment Dates" with respect to this Note shall refer to such dates. The per annum rate of interest payable with respect to this Note will (on and after such Last Monthly Interest Payment Date) be reset weekly and will be equal to the Weekly Average Federal Funds Rate (as defined herein), plus 0.10% (ten one-hundredths of one percent). Interest prior to such Last Monthly Interest Payment date will accrue at a rate as specified in the Initial Note Form. Interest payable on each Interest Payment Date will include interest accrued from and including the first day of the Interest Period relating to such Interest Payment Date to and including the last day of such Interest Period. "Interest Period" shall mean the period beginning on and including October 12, 1993 to but excluding November 10, 1993 and, thereafter, each successive period beginning on and including the day after the last day of the preceding Interest Period and ending on but excluding the next succeeding Interest Payment Date. The per annum rate of interest payable with respect to this Note subsequent to the applicable last Monthly Interest Payment Date will be reset as of the Wednesday of each week at a rate equal to the arithmetic average (mean) of the Federal Funds Rates (as defined herein) in effect with respect to each calendar day from and including the second preceding Thursday to and including the next preceding Wednesday (such period is the "Calculation Period", and such average of the Federal Funds Rates is the "Weekly Average Federal Funds Rate"), plus 0.10% (ten one-hundredths of one percent). Such average rate will be based upon the rate of interest applicable to each calendar day in the Calculation Period, which shall equal, for any Business Day within such Calculation Period, the Federal Funds Rate in effect on such Business Day and, for any non-Business Day within such Calculation Period, the Federal Funds Rate in effect on the next preceding Business Day. As used herein, "Federal Funds Rate" means, with respect to any Business Day within a Calculation Period, the rate on such date for Federal Funds as published by the Board of Governors of the Federal Reserve System in "Statistical Release H.15(519). Selected Interest Rates" or any successor publication ("H.15(519)") under the heading "Federal Funds (Effective)" or, if not so published by 9:00 A.M., New York City time, on the Calculation Date pertaining to the applicable Business Day, the Federal Funds Rate will be the interest rate on such Business 2 Day as published by the Federal Reserve Bank of New York in its daily statistical release, "Composite 3:30 P.M. Quotations for U.S. Government Securities" ("Composite Quotations") under the heading "Federal Funds/Effective Rate". If such rate is not yet published by 9:00 A.M. on the applicable Calculation Date, the Federal Funds Rate for such Business Day will be the rate on such date made publicly available by the Federal Reserve Bank of New York which is equivalent to the rate which appears in H.15(519) under the heading "Federal Funds (Effective)"; provided, however, that if such rate is not made publicly available by the Federal Reserve Bank of New York by 9:00 A.M. on the applicable Calculation Date, the Federal Funds Rate will be the last Federal Funds Rate in effect prior to such Business Day. The "Calculation Date" with respect to any Business Day within a Calculation Period shall be the earlier of (i) the tenth calendar day after such Business Day or, if such day is not a Business Day, the next succeeding Business Day, or (ii) the Business Day prior to the Interest Payment Date on which such accrued interest will be payable. Interest on the Notes will be computed and paid on the basis of the actual number of days for which interest accrues in each Interest Period divided by 360. The Calculation Agent will, upon the request of the Holder of any Note, provide the interest rate then in effect. The Calculation Agent is Merrill Lynch, Pierce, Fenner & Smith Incorporated. All calculations made by the Calculation Agent in the absence of a determination of manifest error shall be conclusive for all purposes and binding on the holders of the Notes. Interest shall be paid on each Interest Payment Date to the Holder of this Note on the Regular Record Date. The "Regular Record Date" shall be the date 15 calendar days (whether or not a Business Day) prior to the applicable Interest Payment Date. If the Maturity falls on a day which is not a Business Day as defined below, the payment due on such Maturity will be paid on the next succeeding Business Day with the same force and effect as if made on such Maturity and no interest shall accrue with respect to such payment for the period from and after such Maturity. The interest so payable and punctually paid or duly provided for on any Interest Payment Date will as provided in the Indenture be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such Interest Payment Date. Any such interest which is payable, but not punctually paid or duty provided for on any Interest Payment Date (herein called "Defaulted Interest"), shall forthwith cease to be payable to the registered Holder on such Regular Record Date, and may be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to the Holder of this Note not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner, all as more fully provided in the Indenture. Payment of the principal of and interest on this Note will be made at the Office or Agency of the Company maintained by the Company for such purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company payment of interest may be made by check mailed to the 3 address of the Person entitled thereto at such address as shall appear in the Security Register. Notwithstanding the preceding sentence, payment of principal of and interest payable at maturity on this Note shall be made by wire transfer of immediately available funds to a designated account maintained in the United States upon (i) receipt of written notice by the Trustee from the Holder hereof not less than one Business Day prior to the due date of such principal payment and (ii) presentation of this Note to the Trustee. The Holder of not less than $1,000,000 Notes may by written notice to the Trustee (or at such other address as the Company shall give notice in writing) not less than 15 days prior to an Interest Payment Date, arrange to have the interest payable on all Notes held by such Holder on such Interest Payment Date, and all subsequent Interest Payment Dates until written notice to the contrary is given to the Trustee, made by wire transfer of immediately available funds to a designated account maintained in the United States.

MEDIUM-TERM NOTE, SERIES B (Nine Month Renewable Floating Rate) MERRILL LYNCH & CO., INC., a Delaware corporation (the "Issuer" or the "Company", which terms include any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to , or registered assigns, the Principal Amount of this Note (as indicated above) on the Maturity Date (as indicated above, which shall not be later than October 9, 1996), and to pay interest thereon, as described below, until the principal hereof is paid or duly made available for payment. This Note is a part of a series of Notes originally issued by the Company on October 12, 1993. Pursuant to the terms of such Notes, the Option to Elect Termination has been exercised with respect to this Note, and this Note shall mature on the Maturity Date specified and have the terms and conditions specified herein. The form of this Note as originally issued by the Company, which governed the terms and conditions hereof prior to the exercise of the Option to Elect Termination (the "Initial Note Form"), is attached as Annex 1 hereto. Terms used but not defined herein but which are defined in the Initial Note Form shall have the meanings provided therein. Interests in this Note (which are sometimes referred to herein where the context so requires as the "Notes"), and any certificated Notes which may be issued in exchange herefor pursuant to the terms hereof, are issuable in denominations of $100,000 and integral multiples of $1,000 in excess thereof. The Notes are not subject to redemption at the option of the Company prior to maturity. Interest on this Note will be payable on each monthly Interest Payment Date to and including the Interest Payment Date (as provided in the Initial Note Form) applicable to the Election Period relevant to this Note (the "Last Monthly Interest Payment Date"), and thereafter on the second Wednesday of the third month and sixth month following the Last Monthly Interest Payment Date, and at maturity. "Interest Payment Dates" with respect to this Note shall refer to such dates. The per annum rate of interest payable with respect to this Note will (on and after such Last Monthly Interest Payment Date) be reset weekly and will be equal to the Weekly Average Federal Funds Rate (as defined herein), plus 0.10% (ten one-hundredths of one percent). Interest prior to such Last Monthly Interest Payment Date will accrue at a rate as specified in the Initial Note Form. Interest payable on each Interest Payment Date will include interest accrued from and including the first day of the Interest Period relating to such Interest Payment Date to and including the last day of such Interest Period. "Interest Period" shall mean the period beginning on and including October 12, 1993 to but excluding November 10, 1993 and, thereafter, each successive period beginning on and including the day after the last day of the preceding Interest Period and ending on but excluding the next succeeding Interest Payment Date. The per annum rate of interest payable with respect to this Note subsequent to the applicable Last Monthly Interest Payment Date will be reset as of the Wednesday of each week at a rate equal to the arithmetic average (mean) of the Federal Funds Rates (as defined herein) in effect with respect to each calendar day from and including the second preceding Thursday to and including the next preceding Wednesday (such period is the "Calculation Period", and such average of the Federal Funds Rates is the "Weekly Average Federal Funds Rate"), plus 0.10% (ten one-hundredths of one percent). Such average rate will be based upon the rate of interest applicable to each calendar day in the Calculation Period, which shall equal, for any Business Day within such Calculation Period, the Federal Funds Rate in effect on such Business Day and, for any non-Business Day within such Calculation Period, the Federal Funds Rate in effect on the next preceding Business Day. As used herein, "Federal Funds Rate" means, with respect to any Business Day within a Calculation Period, the rate on such date for Federal Funds as published by the Board of Governors of the Federal Reserve System in "Statistical Release H.15(519), Selected Interest Rates" or any successor publication ("H.15(519)") under the heading "Federal Funds (Effective)" or, if not so published by 9:00 A.M., New York City time, on the Calculation Date pertaining to 2 the applicable Business Day, the Federal Funds Rate will be the interest rate on such Business Day as published by the Federal Reserve Bank of New York in its daily statistical release, "Composite 3:30 P.M. Quotations for U.S. Government Securities" ("Composite Quotations") under the heading "Federal Funds/Effective Rate". If such rate is not yet published by 9:00 A.M. on the applicable Calculation Date, the Federal Funds Rate for such Business Day will be the rate on such date made publicly available by the Federal Reserve Bank of New York which is equivalent to the rate which appears in H.15(519) under the heading "Federal Funds (Effective)"; provided, however, that if such rata is not made publicly available by the Federal Reserve Bank of New York by 9:00 A.M. on the applicable Calculation Date, the Federal Funds Rate will be the last Federal Funds Rate in effect prior to such Business Day. The "Calculation Date" with respect to any Business Day within a Calculation Period shall be the earlier of (i) the tenth calendar day after such Business Day or, if such day is not a Business Day, the next succeeding Business Day, or (ii) the Business Day prior to the Interest Payment Date on which such accrued interest will be payable. Interest on the Notes will be computed and paid on the basis of the actual number of days for which interest accrues in each Interest Period divided by 360. The Calculation Agent will, upon the request of the Holder of any Note, provide the interest rate then in effect. The Calculation Agent is Merrill Lynch, Pierce, Fenner & Smith Incorporated. All calculations made by the Calculation Agent in the absence of a determination of manifest error shall be conclusive for all purposes and binding on the holders of the Notes. Interest shall be paid on each Interest Payment Date to the Holder of this Note on the Regular Record Date. The "Regular Record Date" shall be the date 15 calendar days (whether or not a Business Day) prior to the applicable Interest Payment Date. If the Maturity falls on a day which is not a Business Day as defined below, the payment due on such Maturity will be paid on the next succeeding Business Day with the same force and effect as if made on such Maturity and no interest shall accrue with respect to such payment for the period from and after such Maturity. The interest so payable and punctually paid or duly provided for on any Interest Payment Date will as provided in the Indenture be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such Interest Payment Date. Any such interest which is payable, but not punctually paid or duly provided for on any Interest Payment Date (herein called "Defaulted Interest'), shall forthwith cease to be payable to the registered Holder on such Regular Record Date, and may be paid to the person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to the Holder of this Note not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner, all as more fully provided in the Indenture. Payment of the principal of and interest on this Note will be made at the Office or Agency of the Company maintained by the Company for such purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, 3 that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto at such address as shall appear in the Security Register. Notwithstanding the preceding sentence, payment of principal of and interest payable at maturity on this Note shall be made by wire transfer of immediately available funds to a designated account maintained in the United States upon (i) receipt of written notice by the Trustee from the Holder hereof not less than one Business Day prior to the due date of such principal payment and (ii) presentation of this Note to the Trustee. The Holder of not less than $1,000,000 Notes may by written notice to the Trustee (or at such other address as the Company shall give notice in writing) not less than 15 days prior to an Interest Payment Date, arrange to have the interest payable on all Notes held by such Holder on such Interest Payment Date, and all subsequent Interest Payment Dates until written notice to the contrary is given to the Trustee, made by wire transfer of immediately available funds to a designated account maintained in the United States.

The principal amount of the Note shall be reduced upon any exercise of the Option to Elect Early Termination, all as provided below. Interests in this Note (which are sometimes referred to herein where the context so requires as the "Notes"), and any certificated Notes which may be issued in exchange herefor pursuant to the terms hereof, are issuable in denominations of $100,000 and integral multiples of $1,000 in excess thereof. The Notes are not subject to redemption at the option of the Company prior to maturity. Interest on this Note will be payable on the second Wednesday of each month (each an "Interest Payment Date"), commencing in November 1993, and at maturity. The per annum rate of interest with respect to this Note will be reset monthly on each Interest Payment Date and will be equal to LIBOR (as defined herein), plus 0.05% (five one-hundredths of one percent). Notwithstanding the first paragraph hereof, this Note will mature on the Interest Payment Date occurring in October 1994 unless the maturity thereof is automatically extended with respect to all or a part of the principal amount hereof. During the period beginning on the sixtieth (60th) calendar day immediately preceding, and ending on the thirty-second (32nd) calendar day immediately preceding, each Interest Payment Date (each such period being referred to herein as an "Election Period", and each such Interest Payment Date being referred to herein as the "Interest Payment Date applicable to such Election Period"), commencing with the Interest Payment Date occurring in January 1994, the Holder of this Note will have the option to elect a final Maturity Date (as defined herein) for this Note (or for any interest herein of an authorized denomination) which is the Interest Payment Date occurring on the second Wednesday of the ninth month after the Interest Payment Date applicable to such Election Period.

The date on which such surrender occurs shall be the "Election Date" with respect to portion of this Note as to which the automatic extension shall have been terminated. Upon the exercise of an Option to Elect Termination, the principal amount of this Note subject to such election shall be endorsed by the Trustee on the Schedule hereto, whereupon the principal amount hereof shall be reduced for all purposes by the amount so endorsed. The Trustee shall deliver to the Holder in exchange therefor a new Note (substantially in the form of Annex 1 hereto) imprinted with a legend indicating (i) that an election to terminate the automatic extension of the maturity of such Note has been made, (ii) the Election Date and (iii) the Maturity Date with respect to such new Note. Any Note or Notes issued in exchange for or upon registration of transfer of any Notes so legended shall also be legended to the same effect.

All questions as to whether and when an election to terminate the automatic extension of the maturity of any Note has been made shall be determined by the Company, whose determination shall be final and binding. With respect to any Exercised Note, interest will be payable at such times, and will be calculated by such method, as is provided in the form of Note included as Annex 1 hereto.

"Interest Period" shall mean the period beginning on and including October 12, 1993 to but excluding November 10, 1993 and, thereafter, each successive period beginning on and including the day after the last day of the preceding Interest Period and ending on but excluding the next succeeding Interest Payment Date. This Note will bear interest at a per annum rate equal to LIBOR plus 0.05% (five one-hundredths of one percent), and such rate shall be reset each Interest Payment Date other than at maturity (each such date, together with the original issue date of the Notes, October 12, 1993, being referred to in connection with Notes other than Exercised Notes as an "Interest Reset Date"). "LIBOR" with respect to any Interest Determination Date (as defined below) shall equal the rate which appears on Telerate Page 3750, "British Bankers Association Interest Settlement Rates", under the column entitled "U.S.D.", which appears as of 11:00 A.M., London time, on the applicable Interest Determination Date, for deposits (in United States dollars for a period of one month) commencing on the second day on which dealings in deposits in United States dollars are transacted in the London interbank market (a "London Banking Day") immediately following such Interest Determination Date; provided, however, that if no such rate appears, the Calculation Agent shall request the principal London office of four major banks in the London interbank market selected by the Calculation Agent to provide the Calculation Agent with a quotation of their offered rates at approximately 11:00 A.M., London time, on such Interest Determination Date for deposits (in United States dollars for a period of one month and in a principal amount equal to an amount that is representative for a single transaction in such market at such time) commencing on the second London Banking Day immediately following such Interest Determination Date. If at least two such quotations are provided, LIBOR for such Interest Determination Date shall equal the arithmetic mean of such quotations. If fewer than two such quotations are provided, LIBOR for such Interest Determination Date shall equal the arithmetic mean of the rates quoted by three major banks in The City of New York, as selected by the Calculation Agent, at approximately 11:00 A.M., New York City time, on such Interest Determination Date for loans to leading European Banks (in United States dollars for a period of one month and in a principal amount equal to an amount that is representative for a single 3 transaction in such market at such time) commencing on the second London Banking Day following such Interest Determination Date; provided, however, that if the banks selected as aforesaid by the Calculation Agent are not quoting as described in this sentence, LIBOR will be LIBOR in effect on such Interest Determination Date. "Telerate Page 3750" means the display designated as page "3750" on the Dow Jones Telerate Service (or such page as may replace the 3750 page on that service or such other service or services as may be nominated by the British Bankers' Association for the purpose of displaying London interbank offered rates for U.S. dollar deposits). "Interest Determination Date" with respect to LIBOR shall be the second London Business Day (as defined below) preceding each Interest Reset Date. A "London Business Day" is a day on which dealings in deposits in United States dollars are transacted in the London interbank market. Interest on the Notes will be computed and paid on the basis of the actual number of days for which interest accrues in each Interest Period divided by 360. The Calculation Agent will, upon the request of the Holder of any Note, provide the interest rate then in effect. The Calculation Agent is Merrill Lynch, Pierce, Fenner & Smith Incorporated. All calculations made by the Calculation Agent in the absence of a determination of manifest error shall be conclusive for all purposes and binding on the holders of the Notes. Interest shall be paid on each Interest Payment Date to the Holder of this Note on the Regular Record Date. The "Regular Record Date" shall be the date 15 calendar days (whether or not a Business Day) prior to the applicable Interest Payment Date. If the Maturity falls on a day which is not a Business Day as defined below, the payment due on such Maturity will be paid on the next succeeding Business Day with the same force and effect as if made on such Maturity and no interest shall accrue with respect to such payment for the period from and after such Maturity. The interest so payable and punctually paid or duly provided for on any Interest Payment Date will as provided in the Indenture be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such Interest Payment Date. Any such interest which is payable, but not punctually paid or duly provided for on any Interest Payment Date (herein called "Defaulted Interest"), shall forthwith cease to be payable to the registered Holder on such Regular Record Date, and may be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to the Holder of this Note not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner, all as more fully provided in the Indenture. Payment of the principal of and interest on this Note will be made at the Office or Agency of the Company maintained by the Company for such purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto at such address as shall appear in the Security Register.
